A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%
<span>17 1/3 + (-50 1/3) -5 1/2

Cost of 32 ounces yoghurt = $1.62
Cost of 1 ounce = $1.62/32 = $0.05 (approx)
The answer is -3x^2+10xy+8y^2
